Miniature model industrial and commercial photovoltaic power station sand table model making suitable for exhibition display

Case study of sand table model production for industrial and commercial photovoltaic power plants

This project is a sand table model for showcasing industrial and commercial photovoltaic power plants, focusing on the integration of photovoltaic buildings, energy storage, and supporting facilities. It accurately reproduces the layout of power plants and photovoltaic application scenarios, achieving over 90% of real-life reproduction and becoming the core visual carrier for new energy enterprise exhibition halls, trade shows, investment promotion, and technology popularization.

1、 Material selection

The main building adopts ABS sheet and acrylic composite material, balancing structural strength and fine styling; The photovoltaic panel components are made of high transparency acrylic and blue simulated coating materials, simulating the texture and gloss of real photovoltaic panels; Wear resistant PVC sheets and simulated ground stickers are used for roads and venues to restore the paving effect of the factory area; The green area is based on simulated grass, combined with miniature shrubs and street lamp models to create a natural scene; The energy storage equipment and carport structure are made of 3D printed photosensitive resin to ensure precise details and coordinated proportions; The signage and functional instructions are printed using UV printing technology, with clear and durable text that is eye-catching.

2、 Production process

Base construction: take the aluminum alloy box as the bearing base, lay foam boards inside for leveling, divide buildings, roads and green areas, and ensure the overall layout is flat and the proportion is coordinated.

Building and photovoltaic module production: ABS boards are cut and spliced into the main body of the factory and office buildings, and details such as doors, windows, and eaves are restored through polishing and bonding; The photovoltaic panel module adopts a layered process, covering a blue simulation coating on an acrylic substrate, and accurately adhering to the roof and carport surfaces, simulating the arrangement of photovoltaic panel arrays.

Road and greenery construction: laying PVC road boards, drawing lane lines and boundaries; Paste simulated grass, plant micro green plants according to density distribution, and equip them with facilities such as street lights and fences to enrich the scene hierarchy of the factory area.

Assembly of energy storage and supporting facilities: 3D printing of energy storage stations, charging piles and other equipment, bonding and fixing them with the main building, simulating the layout of power station supporting functions; Simulate the route of the circuit using miniature wires to enhance the visual effect of system linkage.

3、 Post processing and coloring

Adopting multi-layer spraying technology, the main body of the building is based on light gray and beige, and the layering of the facade is enhanced through color separation spraying; Spray blue gradient paint on photovoltaic panel components to simulate the gloss and texture of real photovoltaic panels; The road and ground are sprayed with matte gray to avoid reflective interference; Natural transition colors are used in green areas to make the scene more realistic. The surface is sprayed with transparent protective varnish to improve the durability and anti-aging performance of the model, while retaining the texture of the material.

4、 Detail optimization and presentation of effects

Thoroughly polish and adjust the model, repair joint gaps, adjust the spacing between buildings and facilities, and ensure overall proportion coordination; Clean up surface impurities to make the appearance neat and uniform; Embedding micro LED lights to simulate the nighttime lighting effect of photovoltaic power plants and enhance the display atmosphere. The final product presents the planning layout and new energy application scenarios of industrial and commercial photovoltaic power plants through the synergy of materials, processes, and lighting, meeting the needs of enterprise display, investment promotion, and science popularization, and gaining high recognition from customers.
